16 GB is excessive you can save a couple of bucks by dropping down to 8. For your games you don't need a crazy GPU you could go with the r9 380. I tweaked some things mainly the RAM and cpu and mobo.
For an extra 30$ you can upgrade to skylake to future proof but also get a performance boost. PCPartPicker part list / Price breakdown by merchant
